I watched this video about 5 years ago, I found the animations really helped make intuitive sense of the mathematics, something I was ok at in school but never had the interest in it to go any further.

[@RottnRobbie]

Adding to the chorus - THANK YOU! Trig classes were 40+ years ago for me, and this is the first time in my life that anyone ever explained what SIN and COS actually represent! We were just presented with the formulas to calculate them when given a triangle, without even any attempt to explain *why* calculating them is useful, never mind understanding what was being calculated. Lots of practice and testing later, they tossed in secants, tangents, and all the "co-" functions as just more formulae to be memorized and tested on. And although I kinda/sorta got that Radians were a measure of "circular distance", which could be used instead of angle, your visual was the first time it made any sense. Sigh - so many decades wasted without understanding... (BTW - I've been subscribed to your channel for a few years now, but only found it long after 2015. While I very much appreciate all the new content as you manage to post them, this is the first time I've gone back to older videos - and now I wish I'd done it sooner!)

Show yourself I love you

[@deantinney9120]

I enjoy your animated lessons. In 1988, my Engineering School implemented this system into all Electronics Engineering courses. It was all driven by Hypertext, which made it ahead of today's common usage. Each student had an input keypad, used to answer questions and input solutions for the quiz given after every section in each class. They would only proceed to the next module when a required % of the class answered the questions correctly. Sections would be repeated as needed to meet the standard. Our class had a large Honors group. I was disappointed to hear that a couple of years after I graduated, the system was abandoned, citing expense. Apart from the error at 8:30 that you later corrected, this is a good production. I have to vote against any music that plays during narration, as it distracts from the message. Viewers can easily use music in their own environment, if they like it. Those of us who prefer to focus entirely on the subject are unable to mute the music without losing the valuable narration. Without the loud music overlapping the narration, your productions would be excellent for both "styles" of viewers. This style of explanation is very effective and I salute your work! Thank you, these are great tools that I heartily recommend to anyone who asks for help clearing up the topics you cover.

This is a great video I have an 8th grade education and with this I have a decent understanding of trigonometry.

I mean I guess I have a basic understanding of trig now I could easily draw a 3d graph now if I had the information for it. I can see it but I could use a little more in depth information in understanding the calculations and especially for tan cotan sec and cosec.

[@Illubillu]

bubbacoz what do you mean by frequency? Do you mean the period, by any chance?

[@hidejiohira8004]

If i were you, i would find the period. Remember from Physics that T=1/F ; where T=period and F=frequency

[@DanielScheidegger58]

You actually do not need the z-axis to derive the sine. Just introduce a timeline still in two dimensions, then you get the sine curve from the sine value of each angle. In the timeline you have the period between max or min amplitude. From the period on the timeline you can derive the frequency. So, there are some steps which should be explained in between.
